Hi

My table looks like this:

Surname Forename Clss Colour
Anna Archibald A Green
Anna Archibald A Blue
Anna Archibald B Red
Bill Blackman A Red
Bill Blackman B Green
Chris Cardman C Green
Chris CardMan C Blue

I want to return all the records where a person is in the same class
e.g.

Anna Archibald A Green
Anna Archibald A Blue
Chris Cardman C Green
Chris CardMan C Blue

I've got as far as

SELECT surname,forename,class
FROM mytable
GROUP BY surname,forename having count(*) > 1

which returns

Anna Archibald C
Chris CardMan C

Thanks for any help
